Who would have the best chance of victory?

Alright this is a who would have a better chance?

Batman with 5 day of prep vs bloodlusted Dr Strange

Tony Stark with 5 days of prep vs bloodlusted Darkseid

Or

Reed Richards with 5 days of prep vs bloodlusted Kubik

Well the easy answer is Reed clears all opponents.

For me, Tony has the best chance, because in those 5 days, he can use Reed as one of his resources.

But if it's a vs Reed wouldn't help someone else win.

But its a who has a better chance, not a vs. 😛

You ARE right, though. Reed is a douche nozzle, he wouldnt help in a competition.
What i meant was, Reed would likely handle his challenge solo.
Tony would tap other big brains in his prep phase, while forming a plan.
